No, it's not actually a bag, but this stainless-steel tool works just like one, or maybe even better. Think of it as a modern upgrade to the traditional pastry bag, with a large, comfortable handle that you push to dispense pastry cream or icing, instead of a bag that you have to squeeze. It makes the flow of icing consistent and uniform and helps you create distinctive decorations with greater precision. Along with the stainless "bag", you get five small decorating tips, three large tips, a long needle-like filler tip, and tip adapters for both the small and the large tips. Alll the parts are easily disassembled to go in the dishwasher. Recipes and instructions are included.
